Application filed July 3. 1917.

To all whom it may concern:

Be it known that I. Onrvnr. J. SMrrH. e cit" cn of the United StatesofAmerioa, and res lent of Monroe, in the parish of Ouachito and Stateof Louisiana. have invented certain new and useful Improvements inAslnPans, of which the following is a. specification.

This invention relates to steam and furnaces and particularly tolocomotive furnaces, the said invention being directed more particularlyto ash pans for locomotives.

An object of this invention is to orovicle on ash pen which can bereadily attached to or removed from locomotives now in own men use, thesaid invention having for its further object the provision. of novelmeans for maintaining or augmei' ting the supply of air under the grateor grate hers, means being also provided for regulating the said supplyof air.

A further object of this invention is to provide an ash pen in which theashes will gravitate toward the discharge opening thereby facilitatingthe blowing out of the said ashes or the removal of the same from thesaid ash pen. I a

A still further object of this invention is to provide ventilators whichcan control the point at which air is delivered under the ire bed withrespect thereof.

With the foregoing and other objects in view, the invention consists inthe details or construction, and in the arrangement and. combination ofports to he hereinafter more fully set forth and claimed.

in describing the invention in detail re:- erence will be had to theaccompanying drawings formingot this specification wherein likecharacters denote correspond I mg parts in the several views, and inWhich Fignre 1 illustrates a view in elevation of a. fragmentof theexterior of a boiler furnace with the invention applied. thereto;

boilers sides of the ash pen to the front or leach a front view of afrog} "owing Patented t, 1919*. Serial No. 178,4:56.

curved sides 6 suplron the fire box by means of the 7, although anyappropriate means may be supplied for connecting these parts together.The sides have openings 6 therein with which chutes to he hereinafterdescribed communicate.

The sides are tapered. in Width from back to front and the bottom 8 ofthe nth pan has upturned flanges 8 i by fastening-s 9, such as rivets orthe comprising inwardly ported like,

- and the said flanges are tapered in width from the back to front, sothat the bottom is supported in an inclined position from front to back,thus causing the ashes in the pen to gravitate toward the back andfacilitating the discharge of the said ashes when they are blown outunder the usual process for discharging ashes.

The back of the ash pan is closed or guarded by a door 10 mounted onhinges, such as 11 and any suitable means may be supplied for holdingthe doorclosed.

At points intermediate the length of the ventilators are intr0- duccd,the said ventilators comprising hoods or chutes 12 which communicatewith the interior of (he fire box through the openings 6 in said sides.The outer ends of these hoods are open end face the direction of travelof the locomotive so that air may he collected as the locomotive istraveling. The mouths or outer ends 13 of the chutes are preferablyflared so that a greater volume of air is collected and forced into thefire box.

For convenience of illustration, two of the air collectors ar. shownoneech side, althoi'igh these may be modified as to size andconfiguration within predetermined bounds Without departing from thespirit of the invention.

Each of the ventilators is preferably supplied with a damper comprisinga closure i l and a rod 15 journoled in the'-sides of the ventilatorand. the outer end of the said rod has an operating crank 16 on it sothat any suitable means may he provided for rotating the rod andoperoting the valve or damper controlling the supply of air to the firebox.

By reason of the construction, it has been air may he delivereduniformly to the under surface of a lire bed and that to the velocity ofthe air traveling therein, a. forced draft is effected which to a foundthat connected to the sides great extent when the locomotive is inmotion, supplies sufiicient draft without the use of a blower or otherforce draft mechanism.

The construction of the device is comparatively inexpensive and byreason 0' the simple placed on lOCOmotlVes new in common use withoutmaterially increasing the cost.

I claim- In an ash pan for locomotives, sides having openings therein,chutes extending to the sides in communication with the said manner ofattachment it can be openings, said chutes having openings facing:

the direction of travel of the locomotive, a

bottom for the ash pan having side flanges connected to the said sides,the said flanges and said sides being tapered in width from the back tofront whereby the bottom of the pan is on an incline, a door for closingthe ash pan, and a damper in each of the said chutes, said dampercomprising a rod journaled in the sideof the chute and a closure carriedby the said rod.
